Abstract. Fadjar M, Islamy RA, Herawati EY. 2019. Short communication: First record of Arapaima gigas (Schinz, 1822) (Teleostei: Osteoglossomorpha), in the Brantas River, Sidoarjo, East Java, Indonesia. Biodiversitas 20: 3527-3531. The arapaima (= Arapaima gigas) is the largest freshwater fish in the Neotropical region, obligate air-breathing fish that known to reach up to 3 m - 3.90 m in length and 200 kg in weight endemic to the Amazon basin. Arapaima gigas is giant osteoglossomorph and obligate air‐breathing fish and also a native species of the Amazon basin. We present the first record of Arapaima gigas (Schinz, 1822) in Brantas River, Sidoarjo, East Java, Indonesia with diagnostic meristic and morphometrics of the specimens analyzed following Stewart method. Herein, it recorded from the Brantas River basin. This record based on the finding of one live specimen on the tributary of Brantas River basin, and in situ observation of juveniles and adults in the river).

High Prevalence

Branchiurans are parasites from the buccal cavity, gills, skin, and fins of various fish species. The Neotropical region has one of the highest diversity of branchiurans. On Arapaima gigas, only four species of branchiurans have been reported. The present study improves the knowledge on host and geographical range of Dolops striata. Fish were collected from a fish farm in the State of Pará, Brazil. All A. gigas were parasitized by Dolops striata, which were collected from the fins and body surface. This is the first record of D. striata in A. gigas. The high prevalence detected warns the possibility of an increase in the number of D. striata infesting A. gigas, which may cause some problems for fish-farmers.

In this short communication, we report the unusual presence of blind specimens of the non-native <em>Gammarus</em> <em>roeselii</em> Gervais 1835 (Amphioda, Gammaridae) in the sub-lacustrine Ticino River basin (Po River floodplain, Northern Italy). Considering that <em>G</em>. <em>roeselii</em> is present in almost all small semi-natural tributaries of the Ticino River, it is important to carry out further research on this well-established exotic species to verify its genetic variability.

Corbicula largillierti is a native mollusk from China. In Brazil, this species was first recorded in the Pantanal of Mato Grosso. This short communication reports the occurrence of C. largillierti for the first time in the Paraíba river basin (Brazilian semi-arid), and also considers the risk of introduction of other molluscs invaders in this basin due to the diversion of water from the São Francisco River. Densities of individuals ranged from 33 to 65 ind.m-2 (maximum values of 484 ind.m-2) in coarse sediment (gravel, 2-4 mm). The diversion of waters from the São Francisco river can lead to the introduction of new species, enhancing ecological problems in the Paraiba river basin.

Xiphophorus Maculatus

We provide the first record of Xiphophorus maculatus (G&uuml;nther, 1866) in a river basin in the northeastern Brazil. Specimens were collected in the Jaguaribe River basin, Jo&atilde;o Pessoa, Para&iacute;ba state, Brazil. Two hundred eighty-one specimens, corresponding to 143 males and 138 females of X. maculatus, were collected at nine sites along the basin, from 2017 to 2019. Specimens total length ranged from 17.5 to 26.6 mm in males and from 11.7 to 32.7 mm in females. Introduction of non-native species greatly threatens the biological diversity worldwide. When introduced into a new habitat, X. maculatus usually decreases microcrustacean, macroinvertebrate and native fish populations.

<p>            Invasive species are one of the major threats to biodiversity, which is aggravated in poorly known groups, such as<em> </em>cladocerans. <em>Daphnia lumholtzi </em>Sars (Cladocera: Anomopoda: Daphniidae)<em> </em>is currently invading the Neotropical region, and there are few records of this process. Our goal was to predict the invasive scenario for <em>D. lumholtzi </em>in the Neotropics using species distribution modelling and to assess the climatic overlap of the invader with the native species. We trained our MaxEnt model using occurrence records from native and invaded areas and projected it in the Neotropics. Additionally, we compared the climatic niche of some native species with the invader’s niche. Our model showed high environmental suitability in areas connected by the lowland Paraná River Basin (southwestern Brazil, eastern Argentina and Uruguay), in south-central Chile and Atlantic coastal areas. Widely distributed native species showed climatic overlap with the invader, while relict species did not. <em>Daphnia lumholtzi</em> thrives in warm and stable environments (e.g. the Paraná River basin), which of concern because the invader could already be spreading in that area. Native species could suffer due to climatic niche similarity, while natural barriers and local environmental conditions may protect relict species. We urge the need for further studies to understand this invasion process more fully.   </p>

Dilocarcinus Pagei

Brazil has one of the most significant diversity of freshwater fish in the world, and this drives trade and fishing tourism. Several species of sport fish have characteristics and behaviors that favor fishing tourism and its related activities. Live baits are widely used in fisheries across the country, and at the end of fisheries, is common that anglers may release the remaining bait in rivers, lakes or reservoirs. Here we report for the first time the crab Dilocarcinus pagei in the Paranapanema River basin, and list the freshwater species that were introduced similarly. During field samplings between 2012/2016, and 2018/2019, we captured 10 individuals of D. pagei. One female in the Rosana Reservoir; and two juveniles, one female and six males in the Taquaruçu Reservoir. The literature review revealed 16 species used as live bait, the crab D. pagei and 15 fish species. Gymnotiformes were the largest number of species used as live bait. The basins that had introduction cases were in the Upper Paraná, Iguaçu, and Paraíba do Sul Rivers. The Paraguay-Lower Paraná River was the system that contributed with nine species to the most invaded ecoregion in Brazil, the Upper Paraná River basin. Anglers and live bait farmers should be aware of the risks and consequences of these constant introduction actions (propagule pressure), not releasing baits. In addition, the live bait trade must be monitored and controlled to occur only with species in their original river basin.

AIM: This work aimed to describe a first record of Misgurnus anguilicaudatus, Cantor 1842 in São Paulo state, as well as your potential impacts on native populations. METHODS: The specimen was caught by eletro-fishing device, in Itaguapeva river, Ribeira do Iguape river basin, Ibiuna (SP), Brazil. Later, it was fixed in 10% formalin and taken to laboratory for species identification, morphometric data evaluation, diet analysis and stage of gondal maturity. RESULTS: The individual was an adult female, without parasites and with gonads in maturity stage B, which indicates vascularized ovaries and presence of oocytes in vitellogenesis process. The dietary analysis showed that 95.3% of the stomach was occupied by insect larvae. CONCLUSIONS: The diet analysis may suggest food overlap and consequent competition for food with native species of the genera Trichomycterus e Characidium, which consume essentially the same items. Still, the great morphological similarity with native species, especially Siluriformes, could generate competition for shelters. Additionally, the stage of gonadal maturity and a recorded ability of the species on establish invasive populations in different environments raise concerns about the possibility of Misgurnus anguillicaudatus reproduction on the studied site.

Abstract. Puspitarini RD, Fernando I, Setiawan Y, Anggraini D, Rizqi HA. 2021. Short Communication: First record of the cassava lace bug Vatiga illudens (Drake, 1922) (Hemiptera: Heteroptera: Tingidae) from East Java, Indonesia. Biodiversitas 22: 2870-2876. The cassava lace bug, Vatiga illudens (Drake, 1922) (Hemiptera: Heteroptera: Tingidae) is recorded from Indonesia for the first time. This species is found on the abaxial surface of leaves of cassava (Manihot esculenta Crantz, Euphorbiaceae) in several plantations of East Java and heavily infest this plant. Vatiga illudens is native to the Neotropical Region and seems to be the alien species in the Oriental Region. This tingid has already spread over a wide region of East Java, suggesting that the invasion of the lace bug endangers the other regions cultivating cassava.
